Everything You Need to Know About Eating Zucchini: Nutrition, Meaning, and Recipes
The deep green pigment of zucchini skin reveals high concentrations of carotenoids, specifically lutein and zeaxanthin. Unlike beta-carotene, these specific antioxidants accumulate selectively in the human retina, concentrating within the macula lutea to filter high-energy blue wavelengths and protect photoreceptor cells from oxidative degradation.
Laboratory analyses confirm that zucchini skin harbors substantially higher antioxidant levels than the pale inner flesh. Alongside carotenoids, the squash contains superoxide dismutase precursors and polyphenolic compounds that neutralize reactive oxygen species. This cellular protection extends to the vascular endothelium, preventing low-density lipoprotein (LDL) particles from oxidizing and adhering to arterial walls.
